“…[ 19 ] Among healthy individuals, DUSN could be the cause of an unexplained unilateral vision loss. [ 10 ] As in our case, the diagnosis of DUSN is entirely clinical, while serological testing of CSD aids in the diagnosis of ocular bartonellosis.…”

A healthy 35-year-old Malay woman presented with left eye pain for 1 week, and ocular examination showed evidence of panuveitis. She had granulomatous type of anterior uveitis with secondary high intraocular pressure (IOP). Fundus showed optic disc swelling, mild vitritis, and multiple subretinal lesions, which later formed a migratory track. A diagnosis of presumed diffuse unilateral subacute neuroretinitis was made. At the same time, the serology test for Bartonella henselae was positive. The patient was treated with antiglaucoma medicine and topical steroids. An antihelminthic was initially used, and later, an antibiotic for cat-scratch disease was added. In addition, focal laser photocoagulation was performed. After 3 months, her visual acuity improved together with a reduction in inflammation and well-controlled IOP.

“…The pathogenesis of DUSN seems to involve a local toxic effect on the retina from the worm by-products. Severe visual loss is attributed to progressive ganglion cell loss from the host's immune reaction to the toxin [1,6,7]. Early presentation is characterized by diffuse intraocular inflammation with unexplained vitritis, papillitis, and migrating crops of multiple white evanescent retinal lesions.…”

We report two cases of diffuse unilateral subacute neuroretinitis (DUSN) where multimodal imaging was used to assist in locating the nematode. The first case presented with clusters of migrating choroiditis with a suspicious tiny visualized worm noted on serial fundus photography. The second case had an atypical presentation with extensive exudative retinal detachment and a suspicious coiled worm in the subretinal space noted on optical coherence tomography. Both cases received oral albendazole for six weeks while the first case received additional argon laser photocoagulation to the suspected nematode. Both cases showed resolution of the ocular inflammation upon completion of treatment with no further recurrences. DUSN should be suspected in young and healthy patients with unexplained unilateral inflammatory eye disease with severe loss of vision. This series highlights the challenges faced in identifying the nematode in cases with suspected DUSN.

“…A similar observation was made by Kang et al . [8] The live worm was captured on OCTA in the outer retinal slab as it was mobile. However, once the worm was immobilized post PSLP, the OCTA did not pick up the worm.…”

A 46-year-old male presented with best corrected visual acuity (BCVA) of 20/125 in his right eye. Fundus showed disc edema, multiple yellow outer retinal crops, macular edema and a live motile worm in the subretinal space. Diagnosis of diffuse unilateral subacute neuroretinitis (DUSN) was made and pattern scanning laser photocoagulation (PSLP) was performed along with administration of oral albendazole, diethylcarbamazine and corticosteroids. Complete disappearance of the worm was observed at 2 weeks. At last follow up, final BCVA improved to 20/30. Herein, we report role of PSLP in the management of DUSN.
